Chartreuse (pronounced: [ʃaʁtʁøz]) is a French liqueur made by the Carthusian Monks since the 1740s. It is composed of distilled alcohol aged with 130 herbal extracts. The liqueur is named after the Monks' Grande Chartreuse monastery, located in the Chartreuse Mountains in the general region of Grenoble in France. The liqueur is produced in a factory in the nearby town of Voiron (Isère).
Chartreuse gives its name to the color chartreuse. It is one of the handful of liquors that continues to age and improve in the bottle.
